SPECIFICATION forming part of Letters IEatent No. 677,167, dated June25, 1901.

Application filed February 21, 1901. Serial No, 48,253. (No model.)

To (LZZ 1071/0122, it Wmy concern:

Be it known that I, FOREE BAIN, a citizen of the United States, residingat Chicago, county of Cook, and State of Illinois, have invented certainnew and useful lmprovem ents in Railway-Rail Joints; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable persons skilled in the art to which itappertains to make and use the same.

The object of my invention is to provide a rail-joint by means of whichthe abutting ends of the adjacent rails in a railway-track may be sofirmly and intimately held together as to produce a result that, for allintents and purposes, is equal in effect to that of a continuousunbroken rail.

By means of my joint the head of the rail is supported in a verticalposition and a bodily support against lateral strain is also afforded.By providing an unbroken metal support under the base of the ends of therails through the entire length of the joint a vertical relativedisplacement of the rails is prevented. The curved vertical portioncontained between the head and flange and on either side of the rail isreinforced at points where the rails meet, which adds great strength towithstand the transverse vertical and lateral stress and shock to whichthe joint is subjected.

The distribution of metal in the general form and construction of myjoint provides the highest realization of strength, rigidity, andsufficient elasticityfor the purpose designed.

In the drawings, Figure 1 is a side elevation of my joint, showing itapplied to the ends of two abutting rails. Fig. 2 is a plan view of thesame. Fig. 3 is a transverse sectionthrough lines 3 3 of Fig. 1.

In all the figures the same letters of reference indicate similar parts.

Two like sections of my device, which are designated generally as B andB, when placed on opposite sides of the rail and bolted together, asshown, constitute the joint.

a and a and b and b are outward extensions of the rail-base support.

0 and o are vertical curved sections, which form a bearing between thetop surface of the base and the under surface of the head of the rail.These angle-bars are perforated with holes for the admission of thebolts, which also pass through the rail.

Bolts a and are designed to pass through the joint under the base of therail. Between these bolts is a truss a and I) for supporting the centerof the rail. The respective trusses are braced by means of an angle-weba and If. This brace increases the cross-section of the joint at pointswhere the two rails meetf Similar braces in the center of the joint aand I) extend from a point near the top of the vertical curved portionsto the bottom thereof and serve to f urther increase the crosssection atthe point where the two rails meet by adding strength and rigidity tothe joint at the point subjected to the greatest strain. This is afeature of great importance in my invention. By making these braces inthis form great strength is secured, which is desirable, and the metalmay be made thin, so that the malleable effect will extend suflicientlyinto it for the purpose of making the entire metal malleable,homogeneous, and tough.

a and b are bosses on the lower part of the respective sections, throughwhich the bolts o and a, are designed to pass, by means of which thelower part of the joint is forced in contact with the sides of therails. The ribs a a a and a on the section B extend from a point nearthe top of the vertical curved portion to the top of thelaterally-extending extremity of the base-plate a, which passes alsounder the rails A and A. These ribs form rigid braces for supporting thecurved portion in a vertical position and for holding the base-plate inthe proper relation thereto. The laterally-extending base-plate affordsa larger surface in cont-act with the tie upon which the rails rest, sothat the weight which comes upon the rail will not embed the rail intothe tie' on account of the large surface over which the pressure isdistributed. There When the j oint-sections are drawn together by meansof the bolts, the vertical curved IOO portions are wedged in tightlybetween the under surface of the rail and the top surface of the flangeand do not come in contact with the vertical Web of the rail. By thisconstruction the head of the rail is directly supported thereby. Aportion of the vertical stress comes directly through the rail-head andangle-bar and is distributed over a larger surface on the tie by meansof the curved portions, rail-bases, braces, and tie-plates, which alsosustain the rail in a vertical position against lateral thrusts andstrains.

Having described my invention, what I claim as new, and desire to secureby Letters Patent of the United States, is

1. In a rail-joint for securing the ends of rails together, thecombination of two like vertical sections curved outwardly from the webof the rail, each adapted to fit the rail along its entire lengthbetween the under surface of the heads and the flange thereof, arail-base plate under thebase-surface of the rail extendinglongitudinally the entire length of the joint and extending laterally ateach end,forming tie-plates,an intermediate folded portion between saidbase-plate and said curved vertical section, vertical webs connectingsaid vertical section, folded portion and tie-plates, and other verticalWebs connecting said vertical outwardly-curved section and said foldedportion at points intermediate of said tie-plates, substantially as setforth.

2. In a rail-joint for securing the ends of rails together, thecombination of two like curved vertical section, vertical websconnecting said vertical section, folded portion and tie-plates, otherwebs connecting said vertical, outwardly-curved section and said foldedportion at points intermediate of said tie-plates, a perforated bossintegral with each section under the rail, for the reception of a bolt,on each side of the longitudinal center, and a web joining said bossesto form a truss, substantially as set forth.

In testimony whereof I have signed this specification, in the presenceof two subscribing witnesses,this 19th day of February, A. D.
